一种混合型蓝藻处理剂及其制作方法A kind of mixed type cyanobacteria treatment agent and preparation method thereof

技术领域technical field

本发明涉及水处理技术领域，具体涉及一种混合型蓝藻处理剂及其制作方法。The invention relates to the technical field of water treatment, in particular to a mixed cyanobacteria treatment agent and a preparation method thereof.

背景技术Background technique

近年来，随着我国人口数量的不断增加以及工农业生产的迅速发展，需水量迅猛增加，同时水污染越来越严重。水污染是当今世界污染最严重，危害性最大的污染之一，我国污水排放量大，导致太湖等江河湖泊水体中的污染物与日俱增，污染速度已超过湖体自身的净化能力，其中一些含磷、含氮化合物的大量排放，加速了江河湖泊富营养化进程，导致藻类特别是蓝藻的异常繁殖生长，并在水面形成一层蓝绿色而有腥臭味的浮沫即水华，释放恶臭，使水质变坏。大规模的蓝藻爆发，被称为“绿潮”，严重时耗尽水中氧气而造成鱼类的死亡。更为严重的是，蓝藻中有些种类（如微囊藻）还会产生微囊藻毒素（microcystins，简称MCs），大约50%的绿潮中含有大量MCs。MCs除了直接对鱼类、人畜产生毒害之外，也是肝癌的重要诱因。In recent years, with the continuous increase of my country's population and the rapid development of industrial and agricultural production, water demand has increased rapidly, and water pollution has become more and more serious. Water pollution is one of the most serious and harmful pollutions in the world today. The large amount of sewage discharge in my country has led to an increase in pollutants in rivers and lakes such as Taihu Lake. The pollution rate has exceeded the purification capacity of the lake itself. Some of them contain phosphorus. , a large amount of nitrogen-containing compounds, accelerated the eutrophication process of rivers and lakes, led to the abnormal growth of algae, especially cyanobacteria, and formed a layer of bluish-green and fishy-smelling foam on the water surface, that is, blooms, releasing stench. Water quality deteriorates. Large-scale algal blooms, known as "green tides," can deplete the water of oxygen and kill fish. What's more serious is that some species of cyanobacteria (such as Microcystis) also produce microcystins (MCs for short), and about 50% of green tides contain a large amount of MCs. In addition to direct toxicity to fish, humans and animals, MCs are also an important cause of liver cancer.

蓝藻治理工程是一项复杂的系统工程。目前采取的主要方法还是在外环境投入大量的人力物力进行引清冲污、搬迁污染企业等转移污染的方式，并没有从根源上解决污染；在内环境治理方面，尽管国内相继出现了生物法（包括微生物法、动物法、植物法）、化学法各类治理蓝藻的方法及处理剂，但至今仍难以得到广泛、有效的应用，主要原因是现有的治理技术单一、过程复杂、功能性不高等。Cyanobacteria treatment project is a complex system engineering. The main method adopted at present is to invest a lot of manpower and material resources in the external environment to transfer pollution, such as clearing and flushing, relocating polluting enterprises, etc., and has not solved the pollution from the root cause; in terms of internal environmental governance, despite the emergence of biological methods ( Various methods and treatment agents for treating cyanobacteria, including microbial methods, animal methods, and chemical methods, are still difficult to be widely and effectively applied. higher.
